100 weeks from today will be 22 Oct 2026, a Thursday. For half-year projections, double-check whether 100 weeks forward remains within 2024. It seems that 100 weeks from now will bring us back to pre 2023. Please include this into our planning as it impacts both the calendar and fiscal year transitions. For extensive calculations like this, I begin by segmenting the year, then multiple 100 by days to get 700 total days ahead. Then either count 700 from November (but that will take forever). You can also estimate 100 weeks to 3.3333333333333335 months, count from December and get closer to Thursday October 22, 2026.

How we calculated 100 weeks from today

All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how adding 100 weeks to today's date gets calculated on each visit:

  • Started with date inputs: starting point: 21 Nov, Units to add: 100 weeks, and year: 2024
  • Noted your current time of year: 9 days in end of November
  • Added 100 weeks from current day: 21 Nov, factoring in there are 9 days left in before December
  • Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2024 fiscal calendar.

Ways to calculate 100 weeks from today

  1. Just calculate it: Start with a time from today calculator. 100 weeks is easiest solved on a calculator. For ours, we've already factored in the days in + all number of days in each month and the number of days in 2024. Simply add your weeks and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
  2. Use November's calendar: Begin by identifying on a calendar, note that it’s Thursday, and the total days in December (trust me, you’ll need this for smaller calculations) and days until next year (double trust me, you'll need this for larger calculations). From there, count forward 100 times by weeks, adding weeks from 21 Nov.
  3. Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+100 into the cell. If you want to add weeks, multiply your day by 7 and months/years will take their own calculation due to the changing days of the week. To find 100 weeks workdays, convert to days but use =WORKDAY(TODAY(), [number of days], [holidays]) into the cell. [number of days] is how many working days you want to add, and [holidays] is an optional range of cells that contain dates of holidays to exclude.

100 working weeks from today

100 weeks is Thursday October 22, 2026 or could be Thursday July 29, 2027 if you only want workdays. This calculation takes 100 weeks and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday October 22, 2026 date.
